CHARLES KING, OF GRAND RAPIDS, MICHIGAN.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 626,466, dated June 6, 1899.

Application filed March 1, 1898. Serial No. 672,208. (No model.)

T0 (064 w/wm it may concern:

Be it known that I, CHARLES KING, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

My invention relates to improvements in the mechanism for adjusting and actuating the pans in a carpet-sweeper; and its objects are, first, to provide a carpet-sweeper having automatically-adj ustable pans, in which each pan may be actuated independent of the other; second, to provide a carpet-sweeper with which each pan may be dumped independent of the other or both may be dumped simultaneously, and, third, to ease the stroke of the handle-bow and prevent pounding when actuating the pan-lever. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a transverse vertical section of my caseon the line '3 y of Fig. 2, showing the distribution and application of the actuating mechanism. Fig. 2 is a sectional plan of one end of a case on the line as a; of Fig. 1. Fig. 3 is an elevation of one end of the case cut away at Z to show the position of the actuating-pin on the end of the handle-bow. Fig. 4 is a plan of the dump-plate; and Fig. 5 is an elevation of the brush-support, showing the application of the actuating-spring.

Similar letters refer to similar parts throughout the several views.

A is the sweeper-case.

A is a slot in the end of the case for the passage of the actuating-pin d on the handlebow.

B represents the wheels, and 1) represents the axles thereof.

0 is one of the pans, the pan on the opposite side of the sweeper being removed from Fig. 1 to show the location of the several actuating-levers, and D is the handle-bow.

To support and actuate the inner edges of the pans, I pivot two angle-levers E to the end of the casein position so that one arm of each extends out and is pivotally connected with the ends of the pans near the inner edges by pins f the other arms extending up and terminating in the bearings e, which when in normal position are held against the pin a by the spring E, so that the movement of the actuating-pin (Z on the handlebow will actuate but one pan at a time, the movement of the pan being effected by throwing the upper end of the lever over to the position indicated by the dotted lines to the left, which throws the inner edge of the pan 0 down by the n10- tion of the pins f to the position indicated by the dotted outline of the pan upon the left side of the case, the return of the pan to normal position being effected by the spring E. a is a pin or stop projecting from the ends of the case between the arms 6 of the anglelevers E to prevent one of said arms from dropping by this point when the other arm is thrown over to actuate the opposite pan, and d is a pin that projects from the hub of the handle-bow through the end of the case and in position to actuate the levers E for raising and lowering the inner edges of the pans, as described. My appliance for supporting and actuating the outer edges of the pans consists of a lever F, pivoted atfto the end of the case immediately back of the pins f of the lever E, the outer end being provided with a pin f, which passes through an aperture in the end of the pan near the outer edge, and the inner end pivoted to the lower end of the connectingrod G, as at i, and the connecting-rod is in turn pivoted at the upper end to the dumplever or segment H, as at g. segment H is pivoted to the end of the case at h, the exact radial center of the segments forming the lever portion of my dump mechanism. The object of this is to bring the lever H inside of the end of the case and to make the aperture through the plate It as small as possible. The segmental levers II are actuated to hold the pans to normal position by the springs I, which are secured to the ends of the case substantially as indicated in Fig. 1 and have spring-arms that extend to and rest upon the ends of the lovers just over the pivot-point g.

To dump the pans, draw the lever H around Q to the position indicated by the dotted lines, and the motion will be transmitted through the connecting-rod G to the end i of the lever F, which being pivoted to the case at f The lever or throws the outer endf,and with it the pan 0, down to the position indicated by the dotted lines at the right of Fig. 1.

I avert the danger of the actuating-pin d striking against the end of the slot A with a sudden jar by placing a spring K to act upon the brush-support J, as follows: I form two loops Z in the guard-plate L, one quite a distance each side of the center of the end of the case,over which I-hook the ends of the spring,

and form a similar loop 76 in the support to receive the center of the spring, so that the tension of the spring will force the support sufiiciently to hold the actuating-pin firmly upon the upper surface of the slot A to cause sufficient friction to prevent the sudden movement of the handle-bow and pin. The position of the pin is more fully shown in Fig. 3 at the point Z.

The guide for the brush-support J is made by striking loops 1 from the guard-plate L.

M represents the drive-Wheel on the brush.

I have not deemed it necessary to show the" brush,as it is built and connected in the usual manner.

The slotj in the brush-support J is for the passage of the actuating-pin d on the handlebow, and the pin'j is for the support of the brush-roll.

When the upper ends of the lever E are held snugly against the pins 0, by the springs E, the levers are so firmly held to place that the pans will always dump in perfect alinement, thus averting the danger of their warping and binding in the case when being dumped, and these springs also assist the springs K to steady the motion of the handle-bow when shifting the machine from one direction to the other, so that pounding is impossible.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a carpet-sweeper, a case, a handlebow, and pans; levers pivoted to the ends of the case, each of said levers having an arm extending horizontally from the pivot-point to engage :the ends of the pans near the front edge, and a vertical arm that extends up to position to engage the actuating-pin .on the handle-bow, a spring and pin for holding said levers to normal position and dumping mechanism, substantially as and for the purpose set forth.'

2. In combination with a carpet-sweeper case, having the ends slotted for actuating the pans, and the handle and pans of a carpet-sweeper, levers pivoted to the case so that each pan is actuated independent of the other, springs and pins for actuating and holding said levers to normal position, levers pivoted at one end to the ends of the pans near the outer edge, thence extended back and fulcrumed to the end of the case and the opposite end pivoted to the connecting-rods G, segmental levers pivoted at their radial center to the inner surface of the end of the case with one end extending up out of the case and the other end pivoted to the end of the connecting-rod G so that the revolving of the segment-lever will actuate the dumping of the pan, and a spring for holding all to normal position, substantially as and for the purpose'set forth.

3. In combination, the case, pans, handlebow and guards of a carpet-sweeper, with independent levers for actuating the inner edges of the pans, springs and pins for actu ating and holding said levers to normal position, a dumping mechanism consisting of a segmental lever centrally pivoted to the frame, a straight lever fulcrumed to the case and pivoted to the pans, a rod connecting said levers for dumping the pans, and an actuating-spring acting thereon, With a spring acting upon the brush-support to force the actuating pin on the handle-bow against the upper surface of the slot in the end of the frame, substantially as and for the purpose set forth.

4:. The combination in a carpet-sweeper of a case, and a handle-bow operating in slots in the ends of the case pans adjustably supported in said case, levers for operating the front edges and a dumping mechanism, with a spring acting upon the brush-roll support to force the actuating-pin on the handle-bow solidly against one of the horizontal Walls of the slot in the'end of the case, substantially as and for the purpose set forth.

5. The combination in a carpet-sweeper, of a case, a dumping mechanism consisting of a lever fulcrumed to the end of the case, and one end pivoted to the end of the pan near the outer edge, a segmental lever centrally pivoted within the case, one end of said lever extending out of the case and the other end pivoted to a connecting-rod that connects it with'the pan-lever, and a spring for holding the whole to normal position, substantially as and for the purpose set forth.

6. In combination with a carpet-sweeper case, and pans pivoted thereto; segmental levers centrally pivoted Within the case one end of said lever extending out of the case and the other end connected by a rod with the pan so that the motion of the lever will dump the pan, substantially as and for the purpose set forth.
